Conclusions
-
1.
It was established by the EPR method that VO2+ ions interact with films based on polyhydroxyphenylbenzoxazoleterephthalamide (PBO) and only form complexes with two units L of the polymer, where the fraction of the PBO units which form VOL2 complexes does not exceed 10%.
-
2.
During the thermooxidation of VO(PBO) films the VO2+ complexes present in them can act as inhibitors and initiators of radical reactions.
